Hi
I am new to the field of audio compression. Could someone explain the
quantization process?.
I see that the spectral value is multiplied
by the following to get the quantized value
(pow(2, (3/16)*scale_factor))*(spectral_value^0.75)
According to my understanding, power-law quantization should be as
follows,
pow_value = spectral_value^0.75;
pow_sc = scale_factor^0.75;
quant_value = pow_value/pow_sc;
Could someone explain the logic behind the formula used in AAC
quantization?
